Que. What are Geoff Green’s reasons for including high school students in the Students on Ice Expedition?
Ans. Geoff Green feels that students are the future generation of policy-makers. They should be provided an opportunity to have this life-changing experience at a young age in order to foster a new understanding and respect for our planet. It would help them to absorb, learn and act for the benefit of the planet. The youngsters still have the idealism to save the world and they need to understand that it belongs to them. So, to sensitize them, it is important to provide them the visible life changing experience.
Que. Why is Antarctica the place to go to understand the Earth’s present, past and future?
The author states that to understand the earth’s present, past and future, Antarctica is the right place to go. Antarctica is relatively untouched in this respect as it has never had human population. It is relatively pristine. It holds in its ice cores half a million-year-old carbon records, trapped in the layers of ice. It embodies all that is pre-historic: cordilleran folds, pre-Cambrian granite shields ozone and carbon: evolution and extinction. The simple eco system and lack of biodiversity indicate how little changes in the environment can have big repercussions.
A visit to Antarctica and witnessing the geological phenomena, such as the drifting of land masses, glaciers receding and ice shelves collapsing makes us understand that global warming is a real threat. Hence, to study the earth’s past, present and future, these factors make Antarctica the best place to go.
